Politicians and civilians alike are sending their best wishes to the U.S. Air Force and the Central Intelligence Agency, with both organizations turning 70 on Monday.

President Donald Trump led the praises of the two groups on his Twitter page. Trump posted a video of his January visit to the CIA, where he called the organization one of country's "most important" groups.

The CIA was created under the National Security Act of 1947, which President Harry Truman signed on July 26, 1947. The CIA officially came into existence on September 18 that same year. Truman appointed the Deputy Director of CIG, Roscoe H. Hillenkoetter as the first Director of the Central Intelligence Agency. One third of the CIA’s personnel were veterans of the World War II-era intelligence service, the Office of Strategic Services (OSS.)

The U.S. Air Force was also a provision of 1947 National Security Act, hence why the two organizations share the same anniversary. The president and First Lady Melania Trump celebrated the Air Force during a weekend appearance at Joint Base Andrews.

"70 years of heroes and 70 years of victory," the president said during the Air Force ceremony over the weekend. “The American people are eternally grateful, we will stand with you always,” Trump added.
